9218 Ishiikazuo           Discovered 1995 Nov. 20 by T. Kobayashi at Oizumi.
Kazuo Ishii (b. 1950), employed in the past in the manufacture of planetaria, has been working since 2005 as an architectural consultant in the design of astronomical facilities. His interest in astronomy was aroused at the sight of Comet 1965 S1 (Ikeya-Seki).
